*** A. File contents ***
Files contain different type 1 diabetes mellitus (T1DM) incidence-related indicators for children and adolescents aged 0-19 for each calendar year from 1990 to 2050.
Indicator names are used as prefixes for each results file, with "Mean" indicating the mean, and "LB" and "UB" indicating the 95% uncertainty intervals (lower/upper bound) of the simulation results
